چکیده

We present the results of numerical calculations of the effects of noise, slippage and superradiance in the UCLA infrared (IR) free electron laser (FEL). The experiment, which uses a high brightness electron beam produced by a photocathode RF gun and a 1.5 cm period planar undulator, will compare the FELevolution starting from noise to that starting from an input signal . Numerical studies indicate that we can observe saturation, optical guiding effects and a superradrant spike .

First Demonstration of a Slippage-dominant Superradiant Free-electron Laser Amplifier

We report the first experimental demonstration of a slippagedominant superradiant free-electron laser (FEL) using an ultrafast seed-laser pulse. We measured the evolution of the longitudinal phase space in the slippage-dominant superradiant regime. With a roughly 1% variation in the electron beam energy, we observed a seed-like fully longitudinal coherence, and a 2% wavelength shift from the se...

Seeded free-electron and inverse free-electron laser techniques for radiation amplification and electron microbunching in the terahertz range

A comprehensive analysis is presented that describes amplification of a seed THz pulse in a single-pass free-electron laser (FEL) driven by a photoinjector. The dynamics of the radiation pulse and the modulated electron beam are modeled using the time-dependent FEL code, GENESIS 1.3. A 10-ps (FWHM) electron beam with a peak current of 50–100 A allows amplification of a 1 kW seed pulse in the fr...

Seeded FEL Microbunching Experiments at the UCLA Neptune Laboratory

Seeded high-gain FELs, which can generate very powerful radiation pulses in a relatively compact undulator and simultaneously modulate the electron beam longitudinally on the seed wavelength, are important tools for the advanced accelerator development. A single-pass 0.5-9 THz FEL amplifier-buncher driven by a regular photoinjector is being built at the UCLA Neptune Laboratory. FEL interactions...

7 Harmonic Buncher Experiment at the Ucla Neptune Laboratory

* UCLA Department of Physics and Astronomy, Los Angeles, CA 90095-1547 # UCLA Department of Electrical Engineering. Abstract Since typically FEL undulator magnets have period length in the cm range, and the normalized magnetic field strength K is usually close to unity to guarantee a good coupling, a very high energy electron beam is needed to access the UV and x-ray region of the electromagnet...

A study of linewidth, noise and fluctuations in a FEL operating in SASE

We study the evolution of the FEL radiation intensity and spectrum starting from noise in the electron beam longitudinal distribution . Due to the slippage both the time and frequency structure of the emitted radiation pulse show a very different behavior when the bunch length is much longer than or of the order of the cooperation length h . The occurrence of superradtant spikes is discussed. W...
